asparagus

Question

We live on the Oregon coast & started asparagus from seed in a green house.
We up potted them to 4″ pots & they are now aprox. 12″ tall.
The question is do we trim the ferns back & leave them in the pots to over winter in the green house or is there a better way. They are very healthy plants.

Thanks in advance.

Answer 1

You could leave in the greenhouse and plant out in spring. They need to have a cold period and you should add extra insulation around them.
Make sure they do not completely dry out.
